GENERAL CHARACTERISTICS
HIGH VOLTAGE / AC USES
• The main applications include live line indicators, AC dividers,
• These applications require:

HV switches and power circuit breakers. Coupling, by-pass-
ing high frequency circuits also use HV ceramic disc capaci-

II dielectrics. Most of these materials except strontium titanate
exhibit a significant non-linearity. Consequently, the capaci-
tance value depends on the voltage across the component
and on the frequency of the applied signal.

Wa = 2ΠFC tg δ V
This shows that improved performances are obtained
when:
- Good dielectric properties (low tg δ) and
- No long term overvoltage are present and
- Capacitors free of “partial discharge” (corona) effect,
up to rated rms voltage.
